Feedback loop means melting ice causes even more melting
Glaciers in Antarctica are melting from the bottom up as warm ocean water seeps underneath the ice.
Chelsea Harvey covers climate science for Climatewire. She tracks the big questions being asked by researchers and explains what's known, and what needs to be, about global temperatures. Chelsea began writing about climate science in 2014. Her work has appeared in The Washington Post, Popular Science, Men's Journal and others.
Glaciers in Antarctica are melting from the bottom up as warm ocean water seeps underneath the ice.
A record-breaking marine heat wave, which scorched the waters off the Australian coast in 2016, has changed the Great Barrier Reef "forever," scientists say. Not only has the reef suffered extensive die-offs, but the types of corals that remain are different and less diverse than they were before.
Wildfires are burning less land worldwide than they used to — and they're emitting less carbon dioxide, new research suggests.
A critical ocean current seems to be slowing down.
It's not just global air temperatures that are heating up. Ocean heat waves are happening more frequently and lasting longer, too — a potential major threat to coral reefs and other marine organisms, according to new research.
